Surgical traction boot having resilient heel pad and medial and lateral straps

Abstract

A surgical boot apparatus for use in surgery involving hip distraction includes a boot shell having a sole portion configured for placement adjacent a sole of a foot of a patient and a calf portion configured for placement adjacent a calf of the patient. Ladder straps are coupled to the boot shell. An instep pad has ratchet buckles to interface with the respective ladder straps. The ratchet buckles are operable to tighten the instep pad against the patient's leg when the patient's leg is situated within the boot shell.

         9 . The surgical boot apparatus of  claim 1 , wherein each ladder strap has a proximal end that is pinned to boot shell to permit each ladder strap to rotate relative to the boot shell about a respective pivot axis. 
     
     
         10 . The surgical boot apparatus of  claim 1 , wherein the boot shell includes a heel-receiving opening located between the sole portion and the calf portion and configured for receipt of a heel of the patient, the calf portion of the boot shell having a plug-receiving opening spaced from the heel-receiving opening, and further comprising a resilient pad having a main portion configured for engaging an Achilles area of the patient and a plug extending from the main portion, the plug being configured for press fitting into the plug-receiving opening of the boot shell to attach the resilient pad to the boot shell, the main portion including an end region that extends into the heel-receiving opening, and the end region having an end edge including a notch configured for receipt of a calcaneus of the patient. 
     
     
         11 . The surgical boot apparatus of  claim 10 , wherein the plug of the resilient pad is formed integrally with the main portion. 
     
     
         12 . The surgical boot apparatus of  claim 11 , wherein the resilient pad is made of silicone rubber. 
     
     
         13 . The surgical boot apparatus of  claim 10 , wherein the heel-receiving opening is defined, in part, by a U-shaped edge of the calf portion of the boot shell and wherein the resilient pad includes a U-shaped lip having a groove that receives the U-shaped edge of the calf portion. 
     
     
         14 . The surgical boot apparatus of  claim 13 , wherein the U-shaped lip is formed integrally with the main portion. 
     
     
         15 . The surgical boot apparatus of  claim 10 , wherein the plug-receiving opening is a triangular opening with rounded corners. 
     
     
         16 . The surgical boot apparatus of  claim 15 , wherein a periphery of the plug is triangular with rounded corners. 
     
     
         17 . The surgical boot apparatus of  claim 10 , wherein the plug-receiving opening is defined by an opening edge and the plug has a peripheral wall formed with a groove that receives the opening edge.
